Team approach for the management of cleft lip & palate patients is very important. Plastic surgeon, oral-maxillofacial surgeon, orthodontist, otolaryngologist, and speech therapist should be included in the team. Main role of the ENT surgeon may be variable and is up to the team characteristics. Main topics of ENT surgeons' interesting fields are evaluation and management of hearing impairment due to SOM, voice disorder, and velopharyngeal incompetency due to submucous cleft palate & still remained VPI after curative palatoplasty. Basic review of anatomy & physiology related with otolaryngologic aspect of velopharyngeal system was done. Diseases related with hyponasality as well as hypernasality were discussed. Diagnostic and therapeutic methods were discussed. Proper management of hearing impairment and speech disorders are important.

Objectives : To compare the voice quality and voice problems of untrained professional voice user groups with that of normal control group without voice problem. Materials and Methods : The sustained vowel sounds of 13 male and 36 female teachers, 46 clergies and 15 telephone operators, and 40 normal male and 20 normal female persons were analyzed, using a videostroboscopy and acoustic analyzer. Together with these analyses, a questionnaire associated with risk factors for current and past voice problems was handed over to the patients. Results : The most common symptom in subjective groups was the voice fatigue. In stroboscopic examination, the professional voice user groups shelved functional voice disorder findings regardless of the Intensity of voice use. In the clergy and teacher using loud voice, vocal polyp, vocal nodule and hyperfunction of laryngeal muscle were frequently observed. In the clergy and telephone operator, jitter and shimmer were significantly increased. In the female teacher, the value of jitter, fundamental frequency variation and fundamental frequency were statiscally significant. However, the voice of male teacher showed no significant findings in the acoustic and aerodynamic studies. Conclusion : In the management of voice problems for untrained professional voice user groups, it is important to find the exact causes and patterns of voice problems, and to be individualized the management according to the causes.

Voice therapy is effective in many voice and speech disorders. However, patients have low accessibility to therapeutic facilities due to disease-unrelated reasons such as lack of time and pandemic of COVID-19. Contactless voice therapy could be an alternative and may helpful to all patients with voice and speech problems. We developed contactless voice and speech therapy program on the necessity of improving accessibility. Herein, we report the first case of voice therapy to 30 year-old female patient who complained voice change after total thyroidectomy using contactless voice and speech therapy service platform in Korea.

본 논문은 임상에서 음성장애 환자의 객관적 음성 분석 대상으로 주로 쓰이는 모음연장 발성이 분석하는 구간에 따라 어떠한 음향학적 차이를 보이는지 밝히고자 하였다. 본 연구에서는 성대결절 환자 17명의 /아/ 모음연장 발성을 시작, 중간, 끝 구간으로 편집하여 MDVP를 통해 각 구간의 jitter, shimmer, NHR을 산출하였고, 비교를 위하여 정상 음성 집단 12명의 음성도 분석하였다. 산출 결과는 R 통계프로그램을 활용하여 Fridman test와 사후 검정을 실시하였다. 음성장애 환자집단은 모음연장 발성의 끝 구간이 중간 구간에 비해 jitter, shimmer, NHR 값이 모두 유의하게 높은 것으로 나타났다. 또한, 발성의 시작 구간은 중간 구간에 비해 세 파라미터 모두에서 높게 산출됐지만 유의한 차이는 없었다. 반면, 정상 집단은 발성의 시작, 중간, 끝 모든 구간에서 유의한 차이가 없었다. 모음연장 발성은 구간에 따라 음향학적 파라미터의 분석 결과가 다르고 발성 끝 구간에서 중간 구간보다 유의하게 음성이 불안정해지는 것으로 나타났다. 이러한 결론은 임상 현장에서 모음연장 발성의 분석 구간 선택과 결과 해석에 유용하게 활용될 수 있을 것이다.

우리나라 성인의 현재 흡연율은 감소 추세이지만, 여전히 OECD국가 중에서 가장 높다. 이 연구에서는 2008년 국민건강영양조사에서 이비인후 검진을 완료한 19세 이상 지역사회 성인 3,600명을 대상으로 흡연량이 증가할수록 본인 인지 음성장애의 위험이 비례적으로 증가하는지에 관한 경향성을 분석하였다. 통제변수는 연령, 성, 교육수준, 소득 사분위수, 최장직업, 음주, 최근 2주 동안 만성 및 급성 질환 등으로 인한 통증 및 불편감 여부를 사용하였다. 연구 결과, 고도 흡연(>40.5~55.5 pack year)과 일일 평균 1갑 이상의 흡연은 본인 인지 음성장애의 독립적인 위험요인이었다. 일일 평균 흡연량이 증가할수록 본인 인지 음성장애의 위험이 유의하게 증가하였지만, 평생 흡연량(pack year)은 교차비의 증가가 유의하지 않았다. 본인 인지 음성장애의 조기 선별 및 예방을 위해서 주관적 음성 평가 외에도 추가적으로 현재 흡연량에 대한 조사가 필요하다.

The mucosal bridge of the vocal fold is an arch of mucosa, formed by some portion of the vocal fold mucosa which is detached in various extension and length. The etiology is uncertain but some is related to vocal sulcus. Because it affects the voice with variable impact, it must be differentiated from functional voice disorder. We report a case of a mucosal bridge of vocal fold with a vocal polyp treated by microlaryngeal surgery and voice therapy.

병적인 고음성은 임상적으로 흔하지는 않지만 종종 볼 수 있는 질환으로서 치료에 대한 많은 논란이 있는 게 사실이다. 대개 음성교육에 의한 치료가 많이 시행되며 수술적인 치료로서는 제 3형 갑상연골성형술이 인정되어 온 것이 사실이다. 이러한 수술에 대한 적응증으로는 첫째 남자에서 오랫동안 너무 높은 음성(mutational voice disorder)을 가진 환자와 둘째 여러 가지 원인에 의해 성대가 너무 경직되어 고음이면서 애성(breathy voice)을 동반한 발성장애가 있겠다. (중략)

Voice complication without the laryngeal nerve injury can occur after thyroidectomy. The purpose of this study is to investigate voice changes according to extent of thyroidectomy with acoustic analysis. Thirty-five female patients with papillary thyroid carcinoma took voice evaluation at before and 1 month, and 3 months after thyroidectomy. Acoustic analysis parameters were speaking fundamental frequency(SFF), min $F_0$, max $F_0$, dynamic range $F_0$, jitter, shimmer, noise-to-harmonic ratio(NHR), and Cepstral prominence peak(CPP). Repeated-measured analysis of variance was applied. Time-related voice changes showed significant differences in all parameters except NHR. At 1 month after surgery, voice quality was worse and pitch was decreasing, but voice quality and pitch were improving at 3-month follow-up. Voice changes according to the extent of surgery were in SFF, max $F_0$, and dynamic range $F_0$. Time by surgery-related voice change existed only in min $F_0$. The result showed that the severity of voice complication depended on the extend of thyroidectomy which had a negative impact on $F_0$-related parameters. The deterioration of voice quality at 1 month after thyroidectomy may be affected by the loss of thyroid hormone in the blood. The descent of $F_0$-related parameters may be impacted by laryngeal fixation of surgical site adhesion.

Human voice reacts very sensitively to human's minute physical condition. For instance, human voice disorders affect patients profoundly especially in the case of Parkinson's disease. Acoustic tools such as MDVP, can function as an equipment that measures various voice in different objects. Many different approaches have been applied for analyzing the voice disorders for diagnosis of Parkinson's disease. According to the voice data of suspected Parkinson's patients from UCI Machine Learning Repository, it is reported to have 23 people with Parkinson's disease and 8 healthy people. Applying Mahalanobis Taguchi System (MTS) for diagnosis of Parkinson's disease, the correct diagnosis performance is compared to previous research results.

Functional aphonia is a disease in which normal vocal ability is suddenly lost. When voice therapy is started at an early stage, the prognosis is good. However, if the functional aphonia persists for a long time, there is a possibility that the voice disorder may become fixed, though reports of these characteristics are rare. The authors experienced a patient with functional aphonia that occurred in adolescence and lasted for 7 months and reported the result of treatment.
